The answer is dryed air (0,024 W/m.K).
Well, friend, each material has its own conductivity properties. Copper is a great conductor, while rubber and air are poor conductors. Water can conduct electricity but not as well as metals like copper. Remember, every material is unique in its own way, just like every brushstroke on a canvas is special.
Wood is a poor conductor of heat compared to silver, iron, and copper. This is because wood has a lower thermal conductivity, which means it is less efficient at transferring heat compared to the other materials mentioned.
Copper would be the best conductor for the wire to make the bulb brighter, as it allows electricity to flow more easily. Plastic is an insulator and would not conduct electricity, while gold is a good conductor like copper but is less commonly used due to its higher cost.
Styrofoam because it has a thick layer and is a good insulator.Paper and plastic are could alternatives but Styrofoam would work better, therefore glass would be the worst one to use because it would only keep it warm for a couple of minutes.
Not likely unless it is carrying electricity or coming out of the muzzle of a gun. One of our company's products is a copper IUD (Intra-uterine device). In that application, the copper wire slowly dissolves and produces a pharmacological effect so it is regulated as a drug. Otherwise, the worst effect is that copper will turn your skin green.
The last time I checked the worst conductor of electricity is rubber.

The best conductor of heat is silver, followed by copper and aluminum. The worst conductor of heat is typically materials like wood, paper, and plastic.

Copper is a good conductor of electricity due to its high electrical conductivity. It is not effective as an insulator because it allows electricity to flow easily through it. Therefore, a copper pipe would work better as a conductor rather than an insulator.

Bismuth is considered one of the worst conductors of electricity among metals. It has a high electrical resistance and is often used in some applications where a material with low conductivity is needed.
Aluminium is a good conductor of heat.
No.
Since most water is carried to houses through copper pipes, yeah.
the worst conductors of heat are wood, plastic, rubber, and cloth.
Copper wire is the best, glass is the worst. Coins are not bad, aluminium cans are OK for small amounts of current. Modern steel coins are worse than the old coins with copper in them.
